To all whom t may concern Bc it known that I. RoswELLP. (lt'OIJY. a citizen of the United States, resldlng at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Heating Systems, ot' which the following is a specification.

My invention relates to a. heating system, and more particularly to a low pressure or vapor steam heating system for railway cars. The primary object of the invention is to provide a steam heating system suitable for a railway car comprising certain arrangements of the radiating elements and controlling mechanism therefor whereby the amount of heat delivered to the car, or to some portion of or locality in the .car may he readily varied bv increasing or decreasing the amount of iating surface under influence of the heating medium.

A further object is to provide a heating system. having this capacity, which will be especially adapted for the heating of a railway sleeping car, the controlling arrangements being such that the occupant of a section may vary the amount of heat delivered to that section to suit his own taste or re.- quirements. f

A further object `ci the invention 'is to provide a car heating system comprising a. main or primary radiator and two secondary radiators, together with a, single valve or switching device which can be manipulated so that in one position of its operating mem- 'ber the heating medium will he diverted from the main radiator and caused to pass through the two secondary radiators in series, while in another position of the parts of the valve ,device the medium will be directed from the primary radiator through one of the secondary radiators only, and in a.

third position both secondary radiators will be cut out and the medium allowed to pass uninterrwptedly through the main radiator. A further object of the invention is to provide a suitalble three-position valve device for use in aheating system of the character just mentioned, or 1n analogous situations.

The invention consists-in the new and improved constructions, arrangements and devices to be hereinafter described and claimed for carrying out theabove stated objects, and such other incidental objects as will appea-r from the followin description of a preferred embodiment o my invention.

This embodiment is illustrated inthe aocompa-nying drawings, wherein:

The above arrangements constituting my invention are of particular utility when embodied in a car heating system employing vapor or steam at atmospheric pressure as a heating medium, and the invention is illus trated herein as embodied in a system of this type. Referring to the drawings, 25 desi nates a railway sleepingcar provided wit the usual steam train plpe 26'adap1ted to receive steam from the locomotive w ich hauls the car. In Fi 1 I have shown, following the usual prectlce, a heating apparatus. for each side of the car; these apparatus boing identical, it will be suilicient to refer to the apparatus on oneside of the car only. This keep the the car, and two seoondaiy radiators B and C for each berth section 27 of the car. The secondary radiators B and C are connected with each other and with the primary radiator A by a three-position valve or switching device 28. There will of course be one o these valves in each section, and in accordance with the preferred form of my invention, each valve will have associated therewith an operating device 29 (Fig. 8) which will have three positions corresponding to the three positions of the movable member of the valve device, the operating handle 29 beinglocated so as to be within reach of the occupant of the section or of the lower berth when the section is made up.

The arrangementsY for supplying steam at substantially atmospheric pressure to the primary radiator A are the wellknown devices used for vapor car heating systems, and need be described only in a general way. Steam enters the radiator A from the train pipe through a supply pipe 30, 30, 30". It

ows through a pi e 31 forming part of the radiator A, then t rough a return bend section 32, then through a section 33 which extends preferably the entire length of the car, through another ret-urn bend section 34 at the other end of the car, and then through a pipe 35 from which it is directed into suchof the secondary or section radiators as may be open. The water of condensation and any excess of steam outflows from pipe 35 of radiator A through a discharge pipe 36, 36, to the thermostat member of a vapor regulator 37, this vapor regulator being interposed in the ordinary way between sections 30, 30' of the supply pipe and operating to reduce train pipe pressure suiciently to maintain the steam in the radiating coils in service at Vapproximately atmospheric rassure. A four-way valve 38 is interposed tween supply p'pe sections 30, 30", and the two sections 36, 36 of the discharge pipe. This valve, which is manipulated by the car porter, serves to shut oil' steam from the entire apparatus on' one side of the car by short-circuiting pipe section 30 with pipe section 36, the steam in such case flowing through the thermostat chamber of the vapor regulator in amounts just sufficient te 4atter from getting cold and freezing up.

Fig. 2 shows a. portion of the main radiator A arranged against the side wall 39 of when the movable element or valve member tors.

47 is in position to permit a circulation of the medium through both secondary radia- The valve member 47 comprises a lower disk 48 which rests on the bottom 49 of the valve casing, a top disk 50 to which the valve stem 51 is rigidly secured, and two vertical webs 52, 53 which extend between the disks providin the disks with three ports designated X, Z, respectively. The valve member is revoluble and the ends of the webs 52, 53 preferably make a fairly close fit with the inner faces of webs 41, 42, 43, 44, 45 and 46, these faces and the outer faces of the webs being curved.

The valve casing has the upwardly projecting boss 54 internall threaded for a bonnet 55, a spring 56 being interposed between the bonnet and the upper disk 50 of the valve member. The bonnet is formed with an internally threaded recess 57 to receive the threaded end of a gland 58 which surrounds the valve stem 51, a packing'59 bein arranged between the gland 58 and the lionnet 55.` To the upper end of the valve stem 51 is secured a crank 60 connected by a link 61 with a crank62 on the end of a shaft 63 which passes through a bracket 64 arranged on the wall of the cai', and is provided on its upper end with a collar 65 provided with a lug 66 to which is pivoted the controlling handle 29 referred to above. Projecting upwardly -and outwardly from the edge of the upper disk 50 of the valve member is an arcuate boss 67 adapted to coperate with stops 68, 69 on the interior of boss 54. These stops limit the movement of the Jvalve member in opposite directions. For holding the valve member in the intermediate position (that shown in Fig. 5), a locking dog 70 is provided adapted to engage a recess 71 in the edge of the lug 67. The locking dog has a head 72 which slides within a boss 73 formed on the lvalve casing 28. A spiral spring 74 is interposed between the head of the dog and a screw plug 75 in the outer end of the boss 73. l

The lower disk 48 of the valve member is formed with a perforation 76 outside of the web 53, and another perforation 77 between.

web 5.3 and web 52. The bottom portion 49 of the valve casing is formed with a erforation 78 and with an arcuate charme 79 leading to perforation 78. These arrangements provide drainage ports for radiators B and C when one or both of these radiators are cut olf from radiator A.

Operation: The operation of the apparatus will be Ibest understood by reference to Figs. 3, 4 and 5, taken in connectionwith Fig. 1. With the valve iii the position shown in Fig. 4, all three radiators are active., The steam flows from the left hand pipe section of .radiator A into chamber 1 of the valve device, through port X to chamber 2, through secondary radiator- B to chamber 3, through port Z to chamber 4, through radiator C to chamber 5, and ,then through port Y of the valve member lnto chamber 6, and back to the right hand pipe section of radiator A. It will be seen that with both secondary radiators active, the flow of the circulation through these two ,radiators is consecutive; that is, the steam must pass first through one and then through the other. Furthermore, before the steam can continue its course along the primary radiator A, it must pass through each and all of the seconda radiators as are open to leceive -steam. nasmuch as the throttl ing of the high pressure steam by the vapor regulator takes place only when steam reaches the thermostat chamber of the regulator, which is arranged at the end of the discharge radiator A beyond the last of the section control val`ves28, it is apparent that there can be no short circuiting of an part of the radiating system. So long` as t ere is en abundance Aof steam in the train pipe, all of the radiating ipes which' are open for service are kept fi led with Steam at atmosphe'ric pressure, or slightlyl above.

The main radiating coil A runs substantially the entire length of the 'car andis arranged in proximity to the water` ipes and water fixtures of the car, with t e purpose of protecting these pipes and fixtures from freezing. In the arrangement described, the" steam will necessarily ass the whole length of the car through ra iator A before it'bln drawn off into any of t'he `secondary radiators' B and C. By this arrangement, in case there is a shortage of steam, what steam is available will be used first for the neral heating of'the car and rotection of e water ipes and fixtures be ore any secondary radiator can be supplied. The web 41 between chambers 1 and 6 is preferably formed near the bottom with a `small perforation 80 which-.allows the water of condensation to flow through radiator A even when the valve is in position-fte direct the Steam through one or both of the secondary radintors.

. Withl the valve' meinber 47 turned the position indicated in' Fig. 5, radiator B will be active, but radiator C will be'cut out. The flow of steam will be as follows: From radiator A through port X to chamber 2, through radiator B to chamber 3, and through port Y to chamber 6, 'and thence back to radiator A. When the valve mem; ber is in this position, the drainage opening 76willregister with opening 78 i-n the bottom" of the' halve-casing, thereby providing av drainage port for the water of condensa tion in radiator C.

By turning the valve memberto the positionshown in Fig. 3, both secondary raother pipe leading from the mainA -in a thir Vhaving a revoluble laforesaid pipe so that diators B and C are cut out. The flow of the steam is from chamber 1 through port X to chamber 6. With the valve 1n this position drainage opening 76 communicates with the channel 79 in the bottom member of the valve casing, while 'ening 77 r 'stels with the opening 78 initlie casin his arrangement provides means for raining both of the secondary radiators.
